Online- / offline mode (ONL/OFFL) 

Offline (OFFL): If the settings directly at the pyrometer should be used (emissivity, exposure time and ana-
log output) the pyrometer must be switched into offline mode (OFFL). In the offline mode these parameters 
can not be adjusted via digital interface and PC, they can only be read! This prevents incorrect set-up or 
undesired changes via the interface. All additional available parameters (see 9.2 Settings only  via serial 
interface) always can be altered via serial interface. 

Online (ONL):  
When switched to the online mode (ONL), only the serial interface can be used to set the values for the pa-
rameters - the instrument’s switch settings are ignored. The device is initialized in “online” mode, i.e. it uses 
the last values set via serial interface!

Parameters / Settings

Settings at the pyrometer or via serial interface 

9.1.1 

Emissivity (Emi) 

For a correct measurement it is necessary to adjust the emissivity. This emissivity is the 
relationship between the emission of a real object and the emission of a black body ra-
diation source (this is an object which absorbs all incoming rays and has an emissivity of 
100%) at the same temperature. Different materials have different emissivities ranging 
between 0% and 100% (settings at the pyrometer between 20 and 100%). Additionally the emissivity is de-
pending on the surface condition of the material, the spectral range of the pyrometer and the measuring 
temperature. The emissivity setting of the pyrometer has to be adjusted accordingly. Typical emissivity val-
ues of various common materials for the two spectral ranges of the instruments are listed below. The toler-
ance of the emissivity values for each material is mainly dependent on the surface conditions. Rough sur-
faces have higher emissivities. 
 

 

Note:  

The minimum emissivity setting for the pyrometer is 20%!
